SPECIFICATION forming part of Letters Patent No. 623,260, dated April 18, 1899.

Application tiled October 3l, 1898. Serial No. 695,032, (No model.)

Be it known that I, FRANK SCHOENFELDT, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following isa specification.

My invention relates to certain improvements in windows of what are ordinarily known as the box-frame construction, and is designed to produce a windowin which the sashes and a portion of the frame can be swung inwardly, so as to permit of the ready cleaning of the sashes without the necessity of standing on the outside ofthe window, as is customarily done in washing windows of the ordinary construction where the sashes are not removable.

To illustrate my invention, reference is had to one forni thereof, which is shown in the accompanying sheet of drawings, in which the same letters of reference are used to designate identical parts in all the figures, of which'- Figure lis an elevation ot' the window from the interior and with some of the casing and parts broken away to illustrate the construction. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a similar section, but with the supplemental frame and sashes partly swung out to the position in which the sashes can be washed. Fig. 4 is a plan-view in section on the line Ll of Fig. l. Fig. 5 is a plan view of a portion of the top of the frame, showing the location and arrangement of the pulley-boxes, one of which is in section. Fig. (3 is a sectional detail on the line 6 6 of Fig. l. Fig. 7 is an inverted plan view of one of the pulley-boxes on an enlarged scale, and Fig. 8 is a sectional view thereof on the line 8 S of Fig. 7.

In my improved construction the vertical boxes A,`which contain the weights B, are ofthe ordinary construction, except that the outer surface of their inner sides is plain instead of having the customary parting-strip set therein and the stop-bead fastened thereto. I provide a supplemental frame C, which is of a rectangular shape, except that it has no lower side. Its cross-section is shown in Figs. 3 and 4, where it will be seen that its inner surface has the channels C and C2 cut therein to form the guiding-ways for the sashes D. The cutting out of these ways leaves ridges C3, C4, and C5, which correspond, respectively,to the inner and ou ter stop-beads and the customary parting-strip. This supplemental frame C is hinged, as best shown in Figs. 2'and 3, at its upper end and inner edge to the top cross-piece A" ot the frame. Instead of having the entire supplemental frame arranged to swing out I fasten the lower portions thereof Cb' to the frame, and these portions are separated from the body of the frame,.as will be readily seen, by the cuts C7, which are arranged slanting downward from the outside to the inside of the frame and also from the inside to the outside of the supplemental frame, as will be readily seen from a consideration of Figs.

l and 3. The first outward and downward slant mentioned is given to the cut to permit the swinging portion of the frame to readily disengage itself from the tixed portion when the frame is swung out, while the second slant mentioned is given to the cut to prevent the free ends oi' the swinging portion from swinging inward, and thereby cramping the sashes in their sliding movement. This construction permits of the swinging inward of the supplemental frame about the hinges E, as shown in Fig. 3, to which position the supplemental frame will swing when the lower sash is raised to the position shown in dotted lines in Figs. 2 and 3, and when the catch, to be subsequently described, is released. The supplemental frame can then be swung as muchfarther outward as may be desired to properly clean the sashes. In order to provide for the increased width caused by the insertion of the supplemental frame, instead of employing a single pulley for the weightropes F, I employ a pair of pulleys G, which are conveniently mounted in a frame G', the

details of which are clearly shown in Figs. 7 and 8 and which are suitably set into and secured to the under side of the strip A.' To hold the supplemental frame in place, I may employ any desired form of a catch; but I preferably employ the form best shown in Fig. 6, where it will be seen that I have a metallic strip H set into the side A2 of the frame, against the projecting portion of which the supplemental frame C rests, and this 'strip may be also covered by the hanging stile J. This strip has a screw threaded aperture IOO therein into which the bolt H, which passes through the supplemental frame O, takes. This bolt II is provided with any desired form ot' a head, such as the ring shown, by which it may be turned to secure the supplemental frame in place or release it, as the occasion requires.

The mode of operation of my device will be readily understood from the foregoing description, and while I have shown it as embodied in the construction which I at present consider as best adapted for the purpose it will be understoodthat it is capable of. some modifications-as, for instance, the side A3 of the box-frame might be omitted, as the supplemental frame takes its place when the window is closed.

Other modifications are within the scope of my invention, and I do not desire to be lim-A ited to the exact form shown and described; but

That I claim, and desire to secure by Letters Patent of the United States, is-

1. A windowcomprisinga main frame which is stationary, a three sided supplemental frame in which the sashes are slidingly mounted, hinges interposed between the under side ot' the upper cross-piece of the main frame and the top side of the cross-piece of the supplemental frame by which said supplemental frame is hinged to said main frame, and weights in the sides of said main frame and connected with the sashes by cords passing through apertures in the cross-piece of the supplemental frame so that the weight of the sashes and weights is carried by the main frame, substantially as and for the purpose described.

2. A window-frame comprising a main stationary frame, a three-sided supplemental frame in which the sashes are slidingly mounted, hinges interposed between the underside of the upper cross-piece ot' the main frame and the upper side of the cross-piece of the supplemental frame by which it is hinged to the said main frame, and the pieces C6 forming a stationary continuation of the supplemental frame, but separated therefrom by the inclined cut CT, substantially as and for the purpose described.
